WILD-OATS SEPARATOR.

Specification of Letters Patent.

Application filed April 30, 1913.

Patented Dec. 36, 1913.

Serial No. 764,623.

To all whom it may concern:

Be it known that 1, WILLIAM H. KLAUER, citizen of the United States,residing at Dubuque, in the county of Dubuque and State of Iowa, haveinvented certain new and useful Improvements in Wild -Oats Separators,of which the following is a specification. 1

My invention relates to a machine adapted to separate wild oats and thelike from native oats and other grain.

The object of my invention is to improve known structures designed forthe same purpose, to the end of accomplishing an efiective dislodgmentof Wild oats and the like from the carrying surface and to insure thatthe same are effectively caught when dislodged and discharged from themachine to provide a tangleor scraping frame; adjustment relativelybetween the scraping frame and revolving body, and generally to effectan organization to promote efficiency in the working of the machine, toreduce cost, etc. 1

The detail structural parts and combinations to produce the severalresults are hereinafter more particularly specified.

In the drawings Figure 1 is a perspec tive view of a wild oatsseparator, showing my invention in association, there being a portionbeing broken away for disclosure of 1nter1or parts; Flg. 2 1s asectional view on varied vertical lines; Fig. 3 is a perspective view indetail of a spout or chute adapted to catch wildoats and discharge thesame outside of the machine; Fig. 4: is an exaggerated front perspectiveview of a section taken from the machine and designed particularly toshow the manner of support and relative adjustment of a rotatablecylinder and tangle wires or scrapers, also the general relativeadjustability between said cylinder and the main supporting frame, andFig. 5 is a detail view showing the form of plates adapted to supportthe tangle wires or scrapers.

Referring to said drawings, 2, 2 are standards, are shaped in their mainportions to adapt them to overlie a cylindrical body, to support thesame from a point above said body, the portion 2 of said standards beingsubstantially vertically placed to form legs. 3 are leg portionsextending laterally some distance at a gradual incline, then downwardlyto form the contact support.

4 is a cross bar adapted to connect frame parts formed of standards 2and leg portions 3 at the ends of the device and adapted to be supportedtherebetween.

5 is a cylindrical body or drum rotatably supported in a positioninclined from a horizontal plane and within the frame structure defined.The means for rotatably supporting the drum comprises a shaft 6journaled in bearings as 7 in uprights S, the latter be ing secured atthe upper portion of standards 2; band or belt wheels 9 fixed to shaft5; belts or bands 10 supported and driven from said band wheels andencircling the said drum in a relation to support the latter in asuspended position from said bands.

11 are flanged rings about drum 5 adapted to form a bearing and guidefor the bands.

12 is a crank arm' applied to the end of shaft 6 to turn the same toaccomplish the rotation of drum 5. n

13 is a lining for the entire inner surface ofdrum 5 and may be of somefabric having a heavy nap, as for instance, cotton flannel.

14 are rollersjournaled upon stud extensions 15 from brackets as 16, thelatter be- .ingfixed in a suitable manner to standard 2. Rollers 1darepositioned for bearing relation with the terminal edges of drum 5; tofix the plane of its travel. 4 17 is a hopper supported upon bar 18, thelatter being connected at its ends respectively with vertical bar 19which connects frame parts and with one of the standards 2. 20 is aspout extension from hopper 17 extending some distance interiorly of thedrum and adapted to discharge grain thereinto.

Inso far as I have progressed with this description, I have definedparts heretofore known in the. art, and particularly in the patent toHoiland, No. 1,0545%), except as to the form of frame support. I havereference specially to standards 2 which, it will be observed,accomplish a support with the framing wholly atone side, thereby leavingcomplete clearance on the other side, which is of service and advantagein placement and adjustment of the drum.

Referring again to the drawings, 21 are frames adapted to be positionedand supported at the ends of the drum 5 and in proximity to the surfaceof the fabric therein, said frame parts being formed with are shapedupper edges, as shown in Fig. 5.

Frames 21 may be formed in any suitable manner for the association andconnection of a plurality of cross strand formations relative to thedrum, but in the form I have shown, the are shaped edge which conformsto the arc of the drum, is recessed as at 22, and pins 23 are positionedupon the outer faces of the frames, whereby a wire strand fixed at oneof its ends to one of the frames may be passed from one frame to theother, engaging recesses 22 and ins 23 successively, traversing back andforth longitudinally of the drum to form the entangling or dislodgmentframe.

, The entangling frame, comprising frames 21 and crosswires 24, is amaterial and essential part of my invention, and in its structure andapplication the wires are so spaced apart relatively that the distancebetween each will be less than that of the normal length of a wild oatbody, and the frame is so placed with relation to the surface of thefabric lining the interior ofth'e drum, that 110 grain can pass withoutcontact with wires of the entangling frame. The wild oats or outlawgrain designed to be eliminated-,- is designed to contact with thefirst, and then the other wires of the frame successively untildisengaged, and in arrangement the first wire of the tangle frame withwhich the wild oat body is brought into contact, will generally causeits" dislodgment from the fabric lining; however, if not released, thepassing'of the body under the wire which traverses its inclined portion;will tilt the forward portion of the body upwardly, to be caught by thenext wire before the bearing relation of the first wire thereupon hasceased, and thus in succession of passage relative to said body, if itshould fail to be dislodged by the first wire, it will be caught by thesec- 0nd, and so on relative to the series until disengaged. v

Frames 21 are supported from arms 25 which are fixed to the machineframe by means of bolts as 27, said arms extending outwardly from theirsupports and downwardly at each side of the drum and to a positionsomewhat below thesame. Frames 21 are supported in an adjustablerelation with said arms by means of bolts a's 21 in slots as 21 saidslots being disposed in said arms to eXtend' in'aline through thecentral axis of said drum, and the bolts 21 are squared as shown in Fig.4, orthat portion at least of said' bolts which pass through said slotsand a squared. opening insaid frames 21 is provided so that in anyadjustment ofsaid frames 21, said frames will be directed and guided toa position of said frar'nerelative to the drum in the exact andp'r'operspaced relation. The rollers 28, supported in connection with arms 25,are intended to engage the exterior of the" drum to hold the latter'inimpinging" relation with the belts or bands 10 so as to insure rotationof said drum. To meet the emergency of stretching, these bands or beltsare usually made of leather or other material, that is liable to stretchor that may be shortened through the influence of weather conditions,and to meet this emergency, the rollers 28 are adjustable upon said arms25 by means of' slots 29 in said arms, whereby I am able to meet theemergency of the change in length of said belts or hands. Wheneverrollers 28 are adjusted it becomes necessary to make an adjustment offrames 21: of the tangle frame for the purpose of maintaining the properrelation of the wires of said frame with the surfaceoftheinteriorliningfabric. Adjustment of frames 21 also is necessary for thereason that byusethe nap of the fabric may be pressed down and therefore said armsmustbe moved to maintain the proper spaced relation between said fabricand said wires comprising the tangle frame;

In carrying out my invention, I provide the gravity trou'glr 30, thesame being formed in an integral body, its upper edges adapted tobear inclose relation to the surface of the interior fabric lining for thedrum, and to embrace the tangle frame in. a relation to deflectdislodged bodies to the inclined bottom portion of the trough below. Thetrough is supported from the cross bar portions thereon, as 31, hrapivotal Ie-latlOHWt'S at 81 the lower end of arm 25 therebyaccommodating substantially freedom of movement relativelybetween frames21 and said trough. The forward end 32 of gravitytrotrgh 301s designed,-for convenience in shipment, to terminate at'the edge of the drum soasto obviate any projecting parts. The forward portion, 32 of said troughis supported from the hooked arm 33* in the manner shown in Fig. 1.

3a is an extension adapted to becomnected with spbut portion 32 adetachable' relation and affords a means of carrying the wild oatdischarge from gravity trough 30-32 to aconvenient portion for deposit;V

is a supplemental chute attached to one of the vertical sidewalls ofgravity chute 30 extends laterally therefrom and into fairly closerelation with the" fabric lining of the interior of the drum, extendinglongitudinally of the drum from its rear end and tl iroughout' thegreater portion of length" thereof, and at a forward incline, as shownin the drawings, to induce a gravity discharge therefrom, and saidsupplemental c'hute is designed to catch all grain carried by the movingto a point above said supplemental chute that may drop before reaching?gravity spout 30, and to deliver the same to a" position in the drum tobe further acted upon and to catch up any wild oats that may have thusbeen redelivered thereto.

I have shown herein the form of embodiment of my invention that Iprefer. However, I do not desire to limit myself to the specific formdisclosed, but claim all forms of embodiment thereof that falllegitimately Within the spirit thereof.

\Vhat I claim is:

1.
